In the construction method such as mud shield method and cast-in-place pile method for underground excavation work, a large amount of bentonite mud water with a certain concentration is used to stabilize the excavation wall surface and to transport the excavated soil in fluid. Has been. Direct release of used waste mud (waste bentonite mud) to rivers and sewage at this time is not allowed because it may adversely affect the environment. Water must be discharged into rivers. However, the mud (bentonite) cannot be easily settled and separated, and even if left alone for a long time, only the water on the liquid surface evaporates and dries, and the mud (bentonite) naturally separates and precipitates. There is no such thing. Therefore, after adding and mixing a coagulant, for example, polyaluminum chloride (PAC) or aluminum sulfate as an inorganic coagulant, and sodium acrylate or acrylamide as an organic polymer coagulant to waste mud (disposal bentonite mud), It is carried out that the flocs are left to stand naturally (bentonite) and then the mud (bentonite) is separated and recovered by performing filtration or the like. In addition, a method of precipitating flocs in a settling tank is also practiced.

Furthermore, there is also a method of performing solid-liquid separation by a centrifugal separation method, a filter press method, etc., but many steps must be performed as a post-treatment step of cake-like bentonite, and there is a problem that the apparatus becomes expensive. is there. Further, in particular, in the filter press method and the centrifugal separation method, a batch (batch type) is often used, and industrially advantageous continuous treatment is difficult.

FIG.
First, for example, waste mud is discharged from a waste mud storage tank 1 in which waste mud (waste bentonite mud) discharged from the shield construction method construction site is stored, through a pipe line, and a flow control valve 2 and a flow meter 3 are connected. After that, it is introduced into the static mixer 4. Therefore, the organic coagulant solution is added and mixed from the coagulant tank (A agent tank) 5, and then the inorganic coagulant is added from the other coagulant tank (B agent tank) 7 in the mixing pipe 6. After that, the waste mud containing the two coagulants added and mixed is introduced from the hose inlet of the wound hose floc generator according to the present invention. In the winding hose,
The waste mud slowly passes through, during which the floc formation reaction is promoted, the flocs generated in the hose grow sufficiently in the hose, and the flocs and free water are good in the outlet hose. It is separated into two and is led out of the system. Then, it is supplied to a gravity dehydrator 9 composed of a mesh belt, and immediately separated into generated and matured flocs and separated water, and the flocs remaining on the mesh belt are transferred to a belt press type dehydrator 10 for further dehydration. As a result, the dehydrated cake is loaded onto the waste transfer vehicle such as a dump truck by the belt conveyor 11.
The separated water derived from the mesh belt type gravity dewatering device 9 and the separated water derived from the belt press type dewatering device 10 are introduced into the adjusting tank 12, where pH measurement and SS measurement are performed, and by addition of acid, alkali and the like. After the SS content is removed by neutralization and addition of a coagulant, it is discharged into sewage.
